The present invention relates to adding machines which print on tape theproblems performed.

One object of the invention is to provide for use by shopkecpers a newand improved adding machine having a `greatly extended utility in thatby virtue of featuresincorporated into the machine it also serves as ahighly eiicient means for effortlessly' and rapidly printing nu; mercialprice values on labels -or stickers of substantial size adapted to beplaced on retail items for saler.'v

Another object is to provide a novel adding machine which is conditionedautomatically by insertion into the machine of a special magazineContaining a roll of blank labels to print a single price value on eachof a connected series of labels, which have an individual height greatlyexceeding the vertical spacing between successive amounts tabulated ontape by the machine in performing a problem in addition.

A more specific object is to provide a dual purpose adding and labelprinting machine in which a capability for efficiently and rapidlyprinting price labels is obtained at slight additional cost, as comparedto a conventional adding machine, by using structure in the machine,which provides an extended vertical spacing on tape between successiveproblems in addition, to provide also a desired spacing between pricevalues printed successively on a connected series of blank labels.

Other objects and advantages will become evident from the followingdescription 'of the exemplary form of the invention illustrated in thedrawings, in which:

FIG. l is a partially sectioned perspective view of an adding and labelprinting machine embodying the invention; y'

FIG. 2 is a fragmentary sectional view on an enlarged scale tal/.engenerally along the line 2-2 of FIG. l, and showing a standard roll ofadding machine tape mounted on the machine;

FIG. 3 is a View similar to FIG. 2 but showing a blank label magazinemounted on the machine;

FIG. 4 is a sectional view taken generally along the irregular line 4 4of FIG. 3; p

FIG. 5 shows a section of adding machine tape on which the machine hasrecorded as succession of problems in addition, and

FIG. 6 shows a connected series of price labels printed in the machine.

The electrically powered adding and label printing machine 10 (FIG.V l)forming the exemplary embodiment of the invention illustrated contains acomplete assemblage of conventional adding machine structure capable ofperforming problems in additionand tabulating the problems performed yonprinted tape 12 (FIGS. l and 5). Such adding machine structure isdisclosed, for example, in the patents to Lippert No. 2,318,000, MehanNo. 2,486,959, and Mehan No. 2,362,709.

Successive numerical amounts or items are entered into the machine 1t)by means of a keyboard 14. After entry of an amount in the keyboard 14,the machine is run through an amount entering cycle by a conventionalpower operated cycling means 16,l which is operated upon depression of amoto-r bar 18. During an item entering cycle the amount set into thekeyboard 14 is printed on the tape 12 by tape printing means 20, such asthat disclosed in the previously mentioned Lippert Patent No. 2,318,000.

Successive amounts entered into the machine 10 and 3,632.9,615 PatentedApr. to, 1962 YFIrC-e printed on the tape 12 are normally accumulated inconventional accumulati-ng means in the machine which includesanvacc'umulating register 22, illustrated schematically' in FIGS; 2 and3. After' all the numerical items in a problem in addition have beenentered into the machine, a total is taken from the accumulator register22 by conventional totalizing means which includes a con- Y trol 24therefor (FIGS. 2 and r3) that is interconnected with the machinecycling means, indicated generally by the numeral 16, to run the machinethrough a totalizing cycle in which the printing means 20 prints thetotal on the tape 12 at the foot of the tabulation of the -numericalitems in the problem of addition performed (FIG. 5).

The strip of printed tape 12 illustrated irl-FIG. 5 shows the tabulationof three successive problems' in addition. The totals are the numericalamounts on the tape followed by the letter "F, the T being printed bycon ventionall means in the printing mechanismA 20 which is operated asian incident to aV total taking cycle.

Again with reference to FIG. 5 it will be noted that the tabulations ofsuccessive amounts 26 added are vertically spaced by` a normal linespacing 28 which is just sufficient to acommodate vertically the numbersof one amount and provide a vnormal space vertically between successiveamounts tabulated.l As will presently appear, this normal verticalspacing of successive amounts printed on the tape is provided byconventional tape advancing means (indicated generally by the numeral 38in FIG. 2) forming a part of the printing means 20.

It will be noted further that the first printed amount of each problemin addition has a greatly extended vertical spacing 32 from the printedtotal of the preceding problern (FIG. 5). As shown, the extended space32 in the lower edge of which the rst amount of a problem in addition isprinted is equal to four normal line spacings 28 for printing of anamount value. This leaves three blank line spaces between the total ofone problem and the lirst amount of the next problem providing avertical separation -on the tape 12V between the tabulations ofsuccessive problems in addition. The extended spacing 32 betweensuccessive problems on the tape 12 is providedv by conventional tapeextending means (indicated generally by the numeral 34- in FIG. 2)coacting with the tape advancing means 30 and forming a part of theprinting means 20.

The present invention makes use of the conventional tape extending means34 and tape advancing means 30 in an extremely simple and highlyadvantageous manner in adapting the machine lto print numerical pricevalues on a connected series of blank labels or stickers 36 (FIG. 6),each of which has a height 38 greatly exceeding the normal line spacing28 (FIG. 5) between successive amounts tabulated in a single problem inaddition. Hence it is worthwhile to -describe the basic features of thisstructure here even though it is fully disclosed in previously mentionedLippert Patent No. 2,318,000 to which reference may be made for afurther description of details.

Thus, as shown in FIG. 2, a roll 40 of adding machine tape is fed acrossa shield 42 (FIGS. 2 to 4) and through a throat 44,(FIG. 3) to passaround a platen roller 46 (FIG. 4). The platen roller 46 is disposed onthe upper forward portion of a rocker assembly 48 (FIG. 2) mediallypivoted on a transverse shaft 49 for rocking movement in thecounterclockwise direction (FIG. 2) to effect the printing of anumerical amount on the tape. This counterclockwise printing movement ofthe rocker assembly 48 is elected by a pair of links 50 (only one ofwhich is shown in FIG. 2) having a lost motion pin and slot connection52 to the lower end of the rocker assembly and operated by theoscillatable main shaft 54 form# ing a part of the machine cycling means16.

To render the last amount printed on .the tape visible after eachoperating cycle of the machine, the tape is advancedfour line spacesafter the amount has been printed and before the operating cycle iscompleted. When a series of amounts are being entered for addition, thetape is normally retracted three line spaces before an entered amount isprinted-on the tape, thus providing only a single line space 28 (FIG. 5)between successive amounts tabulated in a problem in addition.

This normal retraction of the tape by three line spaces and subsequentadvancement of the tape through four line spaces during each printingcycle is effected by means of a tape retracting pawl 56 and a tapeadvancing pawl 58 (FIGS. 2 and 3) which coact respectively with aretractingratchet wheel 60 and an advancing ratchet wheel 62 (FIG. 4)connected to the platen 46.

Both pawls 56, 58 are swingably mounted on a pivot 64 spaced from therocker assembly pivot shaft 49 as shown in FIG. 2, and carried by a pawladvancing and retracting bell crank 66 which is also pivotally mountedon the same shaft 49 as the 4rocker assembly. The two pawls 56, 58 arespring biased counterclockwise to normal positions on the bell crank 66,which positions are determined by engagement of the rearwardly extendingtails of the pawls with a sidewardly extending stop lug 68 on the bellcrank.

A pin and slot connection 70 between the bell crank 66 and the link 50enables the link 50 to swing the bell crank 66 and the pawls 56, 58counterclockwise about the pivot 64 during the initial phase of rearwardmovement of the link 50 during which the pin and slot connection 52,between the link 50 and the rocker assembly 48, allows the rockerassembly to remain in its normal position. This counterclockwisemovement of the arm of the bell crank 66, before the rocker assembly 48starts to move counterclockwise, engages the tape retracting pawl 56with the ratchet wheel 60 to rotate the platen 46 counterclockwise (FIG.2) the equivalent of three line spaces. Thus during the ensuingcounterclockwise movement of the rocker assembly effected by continuedrearward movement of the link 50, the tape is properly retracted threeline spaces to provide only a single line space between the amount to beprinted and the amount previously printed on the tape.

After the rocker assembly 48 has moved clockwise back to its normalposition, continued forward movement of the link 50 swings the bellcrank 66 clockwise back toward its normal position, in the course ofwhich the tape advancing pawl 58 operates in engagement with the pawl 62to rotate the platen 46 clockwise the equivalent of four line spaces,making the last printed amount clearly visible as previously mentioned.This is the normal operation of the tape advancing and retracting meansin printing a succession of amounts entered into the machine foraddition.

Moreover, the tape retracting and advancing means operates in the sameway as an incident to the printing of a total taken from the accumulator22. However, the

Y taking of a totalY automatically activates the problem spacing means34 (FIG. 2) which provides an extended spacing on the tape between thetotal of one problem and the rst amount of the next problem.

The problem spacing structure 34 comprises a tape retracting pawl shieldor blocking element 72 pivotally mounted in adjacent concentric relationto the tape retracting ratchet wheel 60 as shown in FIGS. 2 and 4, andspring-biased clockwise to the normal position shown in FIG. 2 in whichthe shield 72 is out of the path of the retracting pawl 56. As anincident to operation of the machine through a total taking cycle, theshield 72 is swung counterclockwise into a retracting pawl blockingposition, shown in FIG. 3, and latched in this position until it isreleased during the next amount entering cycle ofthe machine. v

' The shield 72 is shifted counterclockwise from its inoperativeposition (FIG. 2) to its operative position (FIG. 3) by clockwisemovement of a latching pawl 74 (FIG. 3) medially pivoted on the rockerassembly 4S and having a forward end underlying the shield 72 as shown.The shield 72 is retained in this operative position (FIG. 3) byengagement of the latching pawl 74 in a notch 76 in the shield whichalso holds the pawl against counterclockwise movement by a spring 77connected to the forward end of the pawl. Y

The latching pawl 74 is swung clockwise `during a total taking cycle byengagement of a stud 78 on the rear end of the latching pawl with therear end of a slide 80 which is moved downwardly during counterclockwisemovement of the rocker assembly 48. The medial portion'of the slide 80is slidably mounted on a pin 82 on the rocker assembly 48 that movesdownwardly during counterclockwise movement of the rocker assembly. Theforward end of `the slide 80 connects with a pivot 83 carried by thelower end of the totalizing control lever 24 which is medially supportedon a pivot 84 above the pivot 83. Thus counterclockwise movement of therocker assembly 48 swings the slide 80 clockwise.

During a normal amount entering cycle when the totalizing lever 24 andpivot 83 are in the neutral position shown in FIG. 2, the relation ofthe pivot 83 to the pivot 82 is such that the clockwise movement of theslide 80 during the operating cycle is not suflicient to move thelatching lever stud 78 downwardly to the extent necessary toy latch theforward end of this lever into the retracting dog shield notch 76 (FIG.3). Consequently, during a normal item entering cycle the shield72swings counterclockwise momentarily and then returns to its normalposition. Since this movement of the shield occurs during thecounterclockwise movement of the rocker 48 which is subsequent to thecounterclockwise movement of the arm 66, it does not interfere normallywith operation of the pawl 56 to retract the tape.

To take a total, the control v24 is moved counterclockwise as indicatedby the arrow 86 in FIG. 2. This moves the slide pivot 83 rearwardly inrelation to the pin 82, thus serving to increase the clockwise movementof the slide 80 during the totalizing cycle to the extent that thelatching pawl 74 swings up into the shield notch 76 and retains it inshielding position, as shown in FIG. 3. Thus the retracting pawlblocking shield 72 is retained in its effective position aftercompletion of the totalizing cycle.

During the next item entering cycle, engagement of the tape retractingpawl 56 with the ratchet wheel 68 is blocked by the shield 72, thuspreventing the normal three line retraction of the tape. The ensuingadvancement of the tape through four line spaces after printing of theitem entered provides the previously mentioned extended space 32.between successive problems in addition las shown in FIG. 5.

A normal item entering cycle following a totalizing cycle also releasesthe shield 72 fromV its operative position for spring return to itsnormal position (FIG. 2),

vThis is effected by a shield release pawl 86 pivotally mounted on therocker arm stud 64 and spring biased counterclockwise to the normalposition shown in FIG. 2.. Near the end of counterclockwise movement ofthe crank 66 in the course of an item entering cycle following atotalizing cycle, a forward end of the shield release pawll 86 engagesthe shield 72 in its operative position (FIG. 3) shifting it somewhatcounterclockwise about its axis to release the latching pawl 74 from theshield notch 76. Both the latching pawl i4 and the shield 72 return tonor-v mal position at the conclusion of the cycle. The shield remainsineffective until the machine again goes through a totalizing cycle.

It is also noteworthy that counterclockwise movement ofthe control 24 toinitiate a totalizing cycle shifts the slide 80 rearwardly, causing therear end of the slide to engage the shield release pawl 86 and hold itclockwise to the shield from operative position.

Since all this structure is conventional and' is already present inadding machines used by shopkeepers, its inclusion in the machineembodying applicants invention does not increase the cost of the machineover` that of conventional machines already in use.

At only nominal additional cost', the machine 10 is' so constructed thatit is conditioned automatically upon' the insertion into the machine ofa special magazine 90' containing a blank roll' of perforated' labels toprint a single numerical price on' the successive labels even thoughthey have a height greater than a single line spacing 28 (FIG. 5)between successive tabulated amounts of a. problemin addition, For thispurpose very simple means is provided to activate the'v previouslydescribedl problem 'spacing means 34 (FIGl 2) in the machine as vvanincident' to mounting of the special magazine 90 on the machine and tomaintain this problem spacing mechanism contimiously effective so longas the magazine remains on the machine.

Thus, as shown in FIGS. 2 and 4, a transverse bail" 92 is pivotallymounted in theA rocker assembly14v83 inonderlying relation to the paperthroat 44 as shown in FIG. One end ofthevk bail 92 is non-rotatably ixedtol the previ'- ouslymentioned l'atching pawl 'I4 fory the retractin'g'pawl shield 72` and serves the medial pivotal support for the latchingpawl. The medial portion ofthe baili 9'2y is horizontally offsetrearwardly as shown in FIGS. 2 to 4, to underlie the previouslymentioned shield 42 onthe' rocker assembly 48 which extends rearwardlyyand downwardly from the tape throat 44. 'A i Thev medial odset portion9'4 (FIG. 3') of the bail 92 is exposed rearwardly and upwardly (FIG. 4)through one of a pair of openings 98, 109 in the shield 42;

kThe special magazine 90 adapted to contain a'- rol-l 102 (FIG. 4)V ofblank labels is designed' -to engage the offset bail portion 94 to moveit downwardlyv and forwardly (FIG. 3) to swing the bail 92 clockwise(FIG. 3) auto'- matically as an incident to mounting of the magazine ona special cradle 104 secured to. the rear of` theA machine as shown inFIGS. 3aV and 4.

In the preferred construction shown,y thev cradle 1104 comprises a pairof laterally spaced support plates 106, 108 projecting upwardly from ahorizontal base 1150l and defining at the upper rear corners of therespective plates an aligned pair of notches 112, 114 adapted to receiveopposite ends ot a removable support spindle 1'16 for a roll of regularadding machine tape 40 (FIG. 2) which is mounted on the machine asdescribedwh'enthe machine is to oe usedy as an adding machine.

The label magazine 90, which is substituted in place of the tape roll40, also has a support spindle 118 (FIGS. 3 and 4) opposite ends ofwhich are adapted 'tol tit' into the support plate notches 112 114. Therolll `102 off blank labels is supported on the magazine spindle 11S'between two parallel plates 120, 122' mounted on the spindle 11S inlixed spaced relation to each other in predetermined positions along theaxis of the spindle to provide proper alignment of the label rollI 162with denominational orders of the machine beginning from the right, aswill be more clearly described presently.

As shown, the plate 12h' is secured to the spindle 118 byv a boss 124iclamped tothe spindle by a set screw 126 which provides for adjustmentof the plate 120 along: the spindle. The other plate 122 is removablysupported' on the spindle 11S by a boss 128 and secured to the plate 120in spaced' relation to the latter by a stud 130 in the plate 120 whichsnaps into` a notchl 132l (FIG. 3)' in the plate 122.

The upper forward portion of the" respective plates 120, 122, withreference to FIG. 3, define a pair of forwardly and downwardly extendingprojections 134,` 13.6. which, upon mounting of themagazine'inthe cradle1:04, project through the respective shield openings 9S, 100 as shown.The projection 134'l engages the offset bail portion 94 t'o pivot the'bail 92 and the shield'latching pawl 74 counterclockwise as described.

The sp'ring'4 76 (FIG. 3) connected tothe latching pawl 74 continues tourge the pawl 74y and bail 92 counterclockwise' against the' projection134, thus tending to force the projection 1.34 rearwardly and upwardly.Tosus'tain this' reaction, the rear edges of the respective cradle platenotches 112, 114 are shaped to form forwardly open hooks 1381, 140 whichreceive trunni'ons' 142, 144 of re'- duced diameter on the respectiveextreme ends of the magazine spindle 118. y

The magazine is held against rotation andu'rged upwardly and*rearwardlyVto seat the' trunnions 142, 144 in the hooks 138, by` a bail 146 pivotedto the lower rear portionsof the respective `cradle plates 0106, 108, asshown, and' urged clockwise (FIG. 3)' by springs 148. A cross" bar150011 the upper forward'portion of they bail 146 extends through slots152 in the cradle side plates and nts into a pair of downwardly opennotches 154 in the respeerive magazin-e plates' 120, 122'. Theyieidabnity of the bail 146 facilitates'mounting. and removal of themagazine 90. y i v Y As shown in FIG. 6, the successive labels' 36supplied in the roll 102 (FIG. 4) join each other in a continuousseries. However, jluncture's of adjacent labels are perforated, as'indicated by the numeral 156, and notched at opposite sides' asindicated by the numeral 158. 'I'he labels 36shown` have a widthsufficient to accommodate price markings of four significant figures andhave an individual' height only slightlyv less' than the label width.The labels' are coated on the back with a pressure sensitive adhesiveand are secured to a coated paper strip 160 slightly wider than' thevseries of labels, or they may be gummed labels. y

y The spacing of the magazine plates 12o, 122 is just sufi'cient' toaccommodate the length ofthe roll of labels 102as" determinedv by thewidth of the strip 160 wound in the label roll. The transverse positionsof the magazine plates'1l20, 122 as determined by the spindle 118 in thecradle 104 properly locates the labels 1564 in alignment with the fourlowest denominationalv orders of the printing means 20 (FIGS. 2 and' 3).of thev machine.

The blank labels are threaded. through the throat 44 t (FIG. 3) andjinto the printing mechanism 20 in the same manner as adding machinetape.

The clockwise' shifting movement of the bail 92 from the position shownin FIG. 2 to the position shown in FIG. 4` effected by a mounting ofthe'V label magazine 90 on the machine as described swings the latchingpawl 74 for the retracting pawl disabling shield 72 into the positionshown in FIG. 3. Clockwise movement of the latching pawl 74 from theposition of FIG. 2 to the position of FIG. 3 swings the shield 72 fromits inoperative position (FIG. 2) to its fully operated position (FIG.3) in which itis held by the latching pawl 74. Since the latchin-g pawlA74 is held continuously in the position shown in FIG. 3 so long as thelabel magazine 90 is installed on the machine, the shield 72 is alsoheld continuously in its operativel position.

Thus when the machine is run through an item entering. cycle in whichthe shield releasing pawl 86 (FIG. 2) engages the shield 72 in itsoperative position (FIG. 3) and` moves the shieldl somewhatcounterclockwise (an action which would normally release the latchingpawl 74 for counterclockwise movement which would release the shield)the latching pawl 74 is held in its latchingposition byv thebail 92 andcontinues to' retain the shield in its operative position in which itblocks engagement of the tape retracting pawl 56.

As a consequence, the's'eries of blank' labels 36 fed into the printingmechanism are not retracted during a printing cycle', andi accordinglyare advancedlthe equivalent of four line' spaces' during each printingcycle'. Hence, the machine will function automatically upon operation ofthe motor bar 18 when the magazine' 90` is' installed in -the machinet`oprint a single price value oni each off the label blanks 36, even thoughthe individual labels have a height approximating four line spaces. Toprint a succession of price labels of the same price value, the price isset into the keyboard 14 and the repeat key 162 (FIG. l) set. The motorbar 18 is then depressed and held down while the machine operatesthrough a continuous series of item entering cycles which print pricevalues on the desired number of labels. Then another price value can beentered into the keyboard 14 and the procedure repeated to producelabels for a different item.

The shopkeeper has then only to remove the printed labels from thebacking strip 60` and apply them to the individual items to be sold.

While I have shown a preferred embodiment of my invention, it will beapparent that variations and modifications thereof maybe made withoutdeparting from the underlying principles and scope of the invention.
